Yabusame and Tsubakura find themselves in an unknown dimension. Not find a way out, but it seems like whoever reaches the goal first will get something. Len'en Mugenri (English: Connecting Chain of) is the first game in Len'en series created by Jynx as a freeware. Len'en is very similar to Touhou series made by ZUN, but it features completely new characters, locations and storyline. Evanescent Existence has two playable characters with Extra Mode (can be unlocked by clearing the main game on any difficulty) and Absurdly Extra Mode (can be unlocked once the main game is cleared on Unreal difficulty). There are 6 stages and 2 possible endings.
